If l, m, and n are parallel, solve for x. Type in numerical values only, do not type in x=

Answers

Answer:

x = 11

Step-by-step explanation:

According to proportionality theorem, the transversal is divided proportionally as it cuts across parallel lines l, m, and n.

Therefore:

[tex] \frac{12.8}{x + 5} = \frac{x - 3}{10} [/tex]

Cross multiply

[tex] (12.8)(10) = (x + 5)(x - 3) [/tex]

[tex] 128 = x^2 - 3x + 5x - 15 [/tex]

[tex] 128 = x^2 + 2x - 15 [/tex]

[tex] 0 = x^2 + 2x - 15 - 128 [/tex]

[tex] 0 = x^2 + 2x - 143 [/tex]

Factorise:

[tex] 0 = x^2 - 11x + 13x - 143 [/tex]

[tex] 0 = x(x - 11) +13(x - 11) [/tex]

[tex] 0 = (x - 11)(x + 13) [/tex]

x = 11 or x = -13

We'd take the positive value.

Therefore, the value of x is 11.

Using compound interest, it is found that it would take 11 years for the value of the account to reach $70,900.

What is compound interest?

The amount of money earned, in compound interest, after t years, is given by:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

In which:

A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year.

Hence, the parameters are given as follows:

[tex]A(t) = 70900, P = 37000, n = 365, r = 0.057[/tex]

We have to solve for t, then:

[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]

[tex]70900 = 37000\left(1 + \frac{0.057}{365}\right)^{365t}[/tex]

[tex]\left(1 + \frac{0.057}{365}\right)^{365t} = \frac{70900}{37000}[/tex]

[tex]\left(1 + \frac{0.057}{365}\right)^{365t} = 1.91621622[/tex]

[tex](1.00015616)^{365t} = 1.91621622[/tex]

[tex]\log{(1.00015616)^{365t}} = \log{1.91621622}[/tex]

[tex]365t\log{1.00015616} = \log{1.91621622}[/tex]

[tex]t = \frac{\log{1.91621622}}{365\log{1.00015616}}[/tex]

t = 11.41

Rounding to the nearest year, it would take 11 years for the value of the account to reach $70,900.

At Gloria’s Restaurant, the average diner tips 18% of their total bill. Carter’s bill was $66.50. How much money should Carter tip?

Answers

Answer:

$11.97

Step-by-step explanation:

If Carter were to tip that 18%, then he should give a $11.97 tip.

0.6650 x 18 = 11.97

The amount Carter should tip at the restaurant is $11.97.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, At Gloria’s Restaurant, the average diner tips 18% of their total bill.

Therefore, The amount Carter must tip should be 18% of 66.50 which can be numerically expressed as,

(18/100)×66.50.

= $11.97.

So, Carter should tip $11.97.

Find the ratios x:y:z if x:y=9:10 and y:z=5:3

Answers

Answer:

Step-by-step explanation:

Answer:

x : y : z = 9 : 10 : 6

Step-by-step explanation:

Expressing the ratio y : z = 5 : 3 in fractional form, that is

[tex]\frac{y}{z}[/tex] = [tex]\frac{5}{3}[/tex] ( cross- multiply )

5z = 3y ( divide both sides by 5 )

z = [tex]\frac{3}{5}[/tex] y = [tex]\frac{3}{5}[/tex] × 10 = 3 × 2 = 6

Thus

x : y : z = 9 : 10 : 6

Interest = Principal × rate × time
interest = 1000 × 0.09 × 0.25
Interest = $22.5

2. If a transversal is perpendicular to one of two parallel lines, then it is perpendicular to the other line.





answer choices:

A) It does not need to be included. By leaving it out of the statement, the reader considers three dimensions not just the xy-plane. The two parallel lines would determine a plane. However, the transversal could intersect only one of the lines. This would allow the proof to use the Corresponding Angles Theorem.

C) It needs to be included as it forces the reader to consider only two dimensions, like the xy-plane. The two parallel lines would determine the plane and the transversal would intersect both lines. This would allow the proof to use the Corresponding Angles Theorem.
